@theaterwork … for admit numbers it is probably best to go straight to the source. Students and parents will for the most part have anecdotal/ second hand information.
I know that I am always happy to put prospective students in contact with current students and alums. I imagine that most schools are. You may want to have your child contact schools with questions, and ask if it is possible to be put in touch with a current student or alum via email.
There will be students who are “successful” after school from most programs… and students who are less immediately “successful” from most programs. This may or may not have much to do with the training and connections at a particular school. Commercial viability at a particular time, work ethic, skill set, and student desire to pursue a professional performance career when the dream becomes a reality all come in to play.
I know quite a few alums from Plymouth State, and the ones pursuing professional work in the performing arts seem to be doing well. Off the top of my head I can think of alums working on cruise ships, in regional theatre, touring, etc… I know others who have successfully transitioned into working in arts management.
Plymouth, NH is a cute little NH town, with a nice main street. The college is in the center of town. There is a bus daily that goes to Boston, which is about 2 hours away.
Hope that helps a little 
If your child has questions about James Madison, shoot me PM or an email.
